Not true, Whopity.
An ATZ that is located in Class G airspace is itself Class G, regardless of whether it has ATC or not. And Article 155 of the ANO says that the term 'controlled airspace' within the Order shall be interpreted as 'airspace which has been notified as Class A, Class B, Class C, Class D or Class E'.
